Google Image Search API: Reverse Image Retrieval

First, why do you need a proxy IP to play Google Image Search API?

Folks doing reverse searches with the Google Image Search API often run into theIP blockedThe bad thing is that the server is not able to handle all the requests. Especially when doing bulk operations, the same IP address crazy request, the server directly give you a seal. At this time, you have to rely on proxy IP toDiversification of riskIt's like opening a chain of stores and using a different business license for each store so that they don't get targeted by the business community.

举个真实案例：有个做跨境电商的朋友要批量验证商品图片版权，用自家服务器API，结果三小时就被拉黑。后来换成ipipgo的动态住宅IP池，连续跑了两周都没事。

Second, hand to teach you with proxy IP

Here's a chestnut in Python, focusing on theProxy SettingsPart:

import requests

proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:9020',
    'https': 'http://username:password@gateway.ipipgo.com:9020'
}

response = requests.get(
    'https://www.googleapis.com/customsearch/v1',
    params={'q': 'Image address', 'imgType': 'photo'},
    proxies=proxies
)

Be careful to replace username and password with the credentials you applied in the ipipgo backend. It is recommended to use theirLong-lasting dynamic IPpackages, saving much more than short-lived IPs.

III. Practical experience in avoiding three major pits

1. Don't use free agents.The IPs that are claimed to be free are either tortoise-speed or have been blacklisted by Google, so using them is like opening a safe with a rusty key.

2. IP switching tempo: It is recommended to change IPs every 50 requests, supported by ipipgo's APIsautomatic switchingYou don't have to write your own rotation logic.

3. request header masquerading asRemember to add a random User-Agent, so that Google doesn't find out that it's the same "person" operating the site.

IV. Frequently Asked Questions QA

Q: What should I do if my proxy IP is slow?
A: Go with ipipgo'sBGP transit line，实测能压到200ms以内。如果是图片下载需求，可以开启他们的压缩代理ip功能。

Q: What should I do if the API returns a 403 error?
A: Don't panic, it's a three-step process:
1. Check whether the proxy IP is effective (with ipipgo background)IP Detection Tool)
2. Make sure that the API key is not exceeded.
3. Reduce the frequency of requests to less than 3 per second

Q: What if I need to process a CAPTCHA?
A: It is recommended to add in the codeFailure Retry Mechanism, in conjunction with ipipgo'sReal Verification IP PoolThis type of IP pass rate can go up to 90% or more.

V. Cautions (highlights)

1. Follow the terms of use of Google's APIs, and don't use them for anything illegal.
2. Commercial projects recommending the purchase of ipipgo'sExclusive IP packageTo avoid "clashing" with other users
3. Regularly update the IP pool, it is recommended to change 20% IP resources every month

Lastly, I would like to say one last thing: If you use a good proxy IP, you will have no trouble with reverse searches. It is especially important to choose the right service provider, such as ipipgo, which can provideCondition Monitoringrespond in singingIntelligent RoutingThe first is to save a lot of debugging time. What do not understand can directly poke their technical customer service, the response speed is faster than the delivery boy.
